Title: Defrosting apparatus for a refrigerator
IPC: H01H7/00
Filed: 1977-12-06
Abstract: The invention relates to a refrigeration assembly and particularly to defrosting apparatus therefor. The assembly includes a bellows operated thermostatic motor switch responsive to evaporator temperatures for operating the compressor motor. After a predetermined number of operating cycles of the compressor the defrost apparatus is actuated. There is a linkage between the bellows and the motor switch with a main spring acting thereon to oppose the bellows and a differential spring acting thereon to assist the bellows. The differential spring is made inoperative by the defrosting unit during the defrost setting. The main spring and the differential spring are calibrated so that when both springs are effective the motor switch is actuated at a predetermined evaporator temperature. When only the main spring is effective during the defrost setting the motor switch is actuatable at an evaporator temperature higher than the above referred to temperature.

Title: Feed water preheater
IPC: F28F9/013
Filed: 1979-08-16
Abstract: A feed water preheater has an integral desuperheater and an integral supercooler through which passes the feed water tube bundle. To prevent the penetration of steam into the supercooler at the point where the feed water tube bundle passes from the supercooler into the condensation space through a support plate, the tubes of the tube bundle are surrounded by sleeves which are fixed to the support plate. Steam flowing through the sleeves condenses and fills the sleeves to prevent the entry of steam into the supercooler. Sleeves are also provided at points where the tubes pass between the desuperheater and condensation space to reduce the velocity of steam traveling from the former to the latter. The latter sleeves can be oriented vertically in the case of a vertical preheater, as long as they are longer than the thickness of condensate disposed on the support plate in the condensation space.
